Answer:

$8.72

Step-by-step explanation:

Since the tax rate is 9% of the lunch cost, the tax for this lunch is .72 dollars since 9% of 8 is 0.72(see math below). You add the 0.72 to 8 and the total cost is $8.72.

8 x (9/100) = tax

8 x 0.09 = 0.72

8+0.72 = $8.72

What is the answer to |x-4|<13

VARVARA [1.3K]

Answer:

<h2>The solution is -9 < x < 17.</h2>

Step-by-step explanation:

|x-4|<13.

The above equation means, whatever the actual value of x is, the value of (x - 4) must be greater than - 13 and less than 13.

Hence, -13 < x - 4 < 13 or, -9 < x < 17. The value of x will be in between -9 and 17. The value of x can not be -9 or 17.

What is the volume of the sphere below?

Sindrei [870]

Answer: Option C.

Step-by-step explanation:

The volume of a sphere can be calculated with this formula:

$V=\frac{4}{3}\pi r^3$

Where "r" is the radius.

You can observe in the figure that the value of the radius of this sphere is:

$r=4\ units$

Then you can substitute this radius into the formula $V=\frac{4}{3}\pi r^3$ .

Therefore, the volume of the sphere shown in the figure is:

$V=\frac{4}{3}\pi (4units)^3$

$V=\frac{256}{3}\pi \ units^3$

One number is one third of another number. The sum of both numbers is 16. Find the numbers.

solong [7]

Answer: 4 and 12

Step-by-step explanation:

Let x be the "another number"

Therefore, "one number" is 1/3x

1/3 x + x = 4/3 x

4/3 x = 16

1/3 x = 4

x = 12

Therefore, the numbers are 4 and 12.
